What’s best way to prep potted plants inside without any bugs?

To bring them back in fro outside?

I found some spray at the local Agway store it kills the little nets that hatch out in the soil when you bring the plants back in the fall.

I read, along time ago, to 1) water plant well 2) place the pot and all into a plastic bag 3) close plastic bag tight for 3 day - 5 days. 4) Remove plastic and bring plant in.

THis is a nifty trick- To get rid of bugs in houseplants, push a clove of garlic into the plant's soil. If the garlic sprouts and grows, just cut it back. Spider mites are apt to thrive in warm, dry houses. Frequent misting under the leaves of houseplants will discourage them.
